Metabolic control, food intake and mood during the menstrual cycle in patients with insulin-dependent diabetes.

The impact of menstruation on metabolic control was studied among 20 insulin-dependent diabetics (IDDM) and 20 healthy controls during two menstrual cycles. No systematic fluctuation in glycated protein, blood glucose levels, food intake, intake of mono- and disaccharides, body weight, or mood could be seen during different weeks in the menstrual cycle. A tendency towards menstruation-related variations in the number of insulin reactions and amount of extra injected insulin was observed in the patient group. Levels of glycated protein were significantly (P < 0.05) higher during the premenstruational than during the postmenstruational week, although the difference was small in absolute terms. A poorer mood during the premenstruation weeks (indicating premenstruation syndrome) was associated with a high number of hypoglycemic events (P < 0.01) and frequent changes in insulin doses (P < 0.01). Thus, taken as a group diabetic women do not experience great changes in food intake or metabolic control during the menstrual cycle. This does not exclude the possibility that a small proportion of women have major menstruation related difficulties in controlling their diabetes.
